查询词典 ectotherms

Rates of development and growth Within the nonlethal temperature range the most important effect on ectotherms of temperature is likely to be its effect on rate of development and growth.

&生理 时间&是将温度和时间相结合的一个测量，应用于外温动物，它反应了这些有机体的生长和发育依赖于温度及时间。

All terrestrial ectotherms must conserve water but at high temperatures rates of water loss can be lethal.

所有陆生外温动物必须保持水，但在高温下失水率能够成为致死因子。

But since these are 'ectotherms'- their body temperature is controlled directly by the environment - everyone assumed that the effect was caused by climate altering their metabolic rate.

但是，因为那些是'外温动物'--它们的体温会直接受环境控制--人人都曾认为这样的影响是由于气候改变了它们的新陈代谢速度而引起的

For many years, scientists had assumed that dinosaurs were cold-blooded, or ectotherms, with a slow metabolism that required the sun's heat to regulate temperature.

多年来，科学家们一直猜想恐龙是冷血动物，代谢水平低，需要太阳的热量来调节体温。

High temperatures may lead to enzyme inactivation or the unbalancing of components of metabolism; for example, in plants, respiration may proceed faster than photosynthesis, leading to death, however, the most frequent effect of high temperature on ectotherms is dehydration.

高温可能导致酶失活或代谢组分不平衡，例如植物的呼吸作用快于光合作用而导致死亡。然而高温对外温动物最普遍的影响是引起脱水。

The advantages of being a 'warm' reptile are that no energy has to be expended to produce metabolic heat to keep warm; in other words, if we were warm reptile-like ectotherms, we would save a lot of money on the grocery bill.

温血&爬行动物的优势是，不必消耗能量来产生代谢热量以维持温度。换句话说，如果我们也像这些冷血爬行类一样维持体温，我们就可省下大笔购买食品的花销。&

Ectotherms are organisms such as plants, reptiles and protista which are largely reliant on external sources of heat to raise their body temperature.endotherms are organisms capable of generating heat internally in order to raise their body temperature.

像爬行动物等有机体属外温动物，它们很大程度地依赖于外来的热来提高自己的体温。

High temperatures may lead to enzyme inactivation or the unbalancing of components of metabolism; for example, in plants, respiration may proceed faster than photosynthesis, leading to death, however, the most frequent effect of high temperature on ectotherms is dehydration.

温度阈 高温可能导致酶失活或代谢组分不平衡，例如植物的呼吸作用快于光合作用而导致死亡。

对温度的响应（E2）植物与水（D2）温度与物种分布（E3）动物与水（D3）生态系统格局（S1） High temperatures may lead to enzyme inactivation or the unbalancing of components of metabolism; for example, in plants, respiration may proceed faster than photosynthesis, leading to death, however, the most frequent effect of high temperature on ectotherms is dehydration.

Heat exchange 温度阈高温可能导致酶失活或代谢组分不平衡，例如植物的呼吸作用快于光合作用而导致死亡。然而高温对外温动物最普遍的影响是引起脱水。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
